The new discovery echoes a mission in 1931, when a five-day zeppelin flight sent robots to the stratosphere and redrew the maps of the high Arctic.
A turbulent melt-river pours a million tons of water a day into a moulin, where it flows down through the ice to ultimately reach the ocean.

Polar bears are increasingly seeking sustenance in human trash because of melting sea ice and a loss of hunting opportunities. The result is a rise in human-bear conflict – and dead bears.

Sea ice is thinning at an alarming rate. Snow is shifting to rain. And humans worldwide are increasingly feeling the impact of what happens in the seemingly distant Arctic.
Nearly 60 years after a radiation-leaking reactor was removed from a US Army base on the Greenland ice sheet, the military is exploring portable nuclear reactors again.
Russia is attempting to claim more of the Arctic seabed, an area rich in oil, gas and minerals. It’s also expanding shipping and reopening Arctic bases. Here are two things the U.S. can do about it.

The “last glacial period” saw huge, rapid climate changes. Our new research found they happened all around the world, and each time within just a few decades.
Satellite research confirms its enormous ice sheet is melting faster than most scientists predicted.

Antarctica is no longer the sleeping giant of sea level rise. New research delved into the past and found when the Earth warms, its ice sheets can melt extremely quickly.
